Bit Error

5.Bits (Measure) This ﬁeld selects the number of bits which will be tested.

This number includes only bits that are tested by the selected measurement type.

6. CRC or FE	These ﬁelds determine what data will be displayed.
	Choices	CRC displays cyclic-redundancy-check (CRC) errors.
		FE displays frame erasures.

7.CRC/FE Ratio This ﬁeld displays the result of the CRC or FE ratio after all the bits have been tested.

8.Count or Ratio This ﬁeld determines how the frame erasures or cyclic-redundancy-check (CRC) errors will be displayed.

Choices	Count displays the number of frame erasures or cyclic-
	redundancy-check (CRC) errors.
	Ratio displays the ratio of frame erasures or cyclic-redundancy-
	check (CRC) errors to total frames.

9.Mobile Reports The mobile reports reﬂect the status of the signal the mobile is receiving. These are:

•RX Qual

•RX Lev

10. Mode	This ﬁeld selects the mode of Bit Error measurement.
	Choices	STD this leaves the display as standard, shown above.
		FAST from the cell control screen, this sends the display to the
		Fast Bit Error screen when selecting Bit Error.

11.MS Loopback In normal BER mode, the loop delay is the total Round Trip Delay (RTD) of the Agilent 8922M/S and mobile phone, expressed in speech frames. The correct number of TDMA frames can be determined automatically by making a Bit Error Test using Auto Mode when the bit error ratio is approximately <20%. Then, if faster measurements are desired or if the bit error ratio exceeds 20%, change the mode to manual.

Choices	Burst Delay - range 0 through 15.
	Manual
	Auto
